Abstract
Life Cycle Assessment (LCA) is increasingly used for buildings, however, mostly for post-design evaluation of the environmental impact. To use the results for optimization, LCA has to be integrated in the early design stages. While Building Information Modelling (BIM) is more and more applied in detailed design stages, simple 3D models are typically used to compare design variants in early stages. The objective of this paper is to introduce a simplified, design-integrated method based on these early BIM models with limited information. The early BIM-LCA method uses simple 3D geometry and a parametric LCA model. Methodological simplifications are introduced and a single indicator based on the certification system of the German Sustainable Building Council (DGNB) is used to provide an intuitive real-time feedback for the designer. The method is applied to the conceptional design of a residential neighbourhood. The results highlight the great potential of using simplified LCA to quantify environmental performance for decision-making in early design stages.
